Remove unused type error suppressions

Summary:
This diff was automatically generated by the Pyre per-target upgrade tool.

It removes `# pyre-fixme` or `pyrefly: ignore` comments that are no longer needed because the underlying type errors have been resolved.
Note that it will also aim to ensure type checking runs cleanly, and will add suppressions to existing type errors.
